Fatigue crack growth in a structure exposed to high temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The exhaust nozzle, made of titanium, is the part of a jet engine where the final expansion of the hot gas from the turbine occurs and where the speed of the exhaust gas is further increased to create thrust. During the ...
Fatigue life assessment of the structure with widespread damage exposed to high temperature
(Elsevier Science Bv, Amsterdam, 2020)
The exhaust nozzle represents a part of a jet engine which is crucial to its overall performance, since it accelerates the flow of hot gases out of the engine and creates a thrust. During its long service, it is exposed ...
Determination of the Actual Stress-Strain Diagram for Undermatching Welded Joint Using DIC and FEM
(MDPI, Basel, 2021)
This paper presents new methodology for determining the actual stress-strain diagram based on analytical equations, in combination with numerical and experimental data. The first step was to use the 3D digital image ...
Predicting fatigue crack growth in complex geometries using numerical methods
(Procedia Structural Integrity, 2023)
Fatigue cracks growth in three different wing spar geometries is simulated using xFEM, as the most suitable numerical method for this purpose. The goal of this analysis was to find out how crack paths affect number of ...
Effect of elevated temperatures on mechanical properties of ultra high strength hot work tool steel h11
(Univ Zagreb Fac Mechanical Engineering & Naval Architecture, Zagreb, 2020)
This paper presents an experimental and numerical study into the influence of elevated temperatures on mechanical properties of the heat treated high quality hot work tool steel H11. This steel belongs to a group of alloyed ...
